SHOCK-LOADING MACHINE.

Application filed February 11, 1921.

To all whom it may concern Be it known that I, BERT A. JonNsoN, a citizen of the United States, residing at Wandan in the county of Morton and State of North Dakota, have invented certain new and useful Improvements in Shock-Loading Machines, of which the following is a specification.

This invention relates to agricultural maohinery and the object is to provide a practical, efficient and comparatively simple shock loader of such design and construction that it will pick the grain shocks off the field and elevate them onto a wagon. The invention is clearly illustrated in the accompanying drawings, in which;

Fig. 1 is a top or plan view of the machine, with various parts broken away.

Fig. 2 is an enlarged detail sectional view of a time tip adapted to be used on the gathering prongs 8.

Fig. 3 is a detail sectional view on the line 33 in Fig. 1, looking in the direction of the arrow A.

Fig. 4 is a fragmentary top view of the roller actuating mechanism.

Fig. 5 is a fragmentary sectional view on the line 55 in Fig. 1, looking in the direction of the arrow B.

Fig. 6 is a sectional view of the elevator on the line 66 in Fig. 1, looking in the direction of the arrow C Fig. 7 is an enlarged detail sectional view on the line 7-'? in Fig. 6, looking in the direction of the arrow D. 4

In the various views of the drawings like characters refer to like parts.

Referring to the drawings by reference numerals, 9 designates a frame which is supported mainly on the bull wheel 10 and the side wheel 11. Extending rearwardly from the machine is a heavy tongue 12 which is supported at its rear end on a steering wheel 13, and said wheel 13 is steered by a handle '14 actuated by the operator of the machine who stands on the platform 15. Pivotally mounted at 16 is an evener 17, to each end of which is secured double trees 18 to which are hitched the horses which propel the ma 50 chine.

On the frame 9 is mounted a carrier frame 19 having horizontal side walls 20 and inclined side walls 21. The upper edge of the rear wall 20 is provided with a guard board Serial No. 444,258.

22 which prevents grain bundles from being thrown rearwardly off the carrier.

In the horizontal portion of the carrier frame 19 is rotatably mounted two rollers 23 and 24, and a third roller 25 is mounted inthe upper end of the inclined portion 21. An apron having slats 27 is stretched over said rollers 23, 24 and 25. The ends 28 of each of these slats travel in grooves 29 in the side walls of the carrier frame. At intervals along the length of the apron 26 certain slats 27 thereon, are provided with inner oscillatable rods 30 having integral tines 31 which extend through slots 32 in the slats. The rods 30 are provided at their inner ends with integral fingers 33 which extend at right angles to the direction of the tines 31, (see Figs. 6 and 7 These fingers do not come in contact with any of the rollers 23, 24, 25 as they pass between the ends of the rollers and the carrier frame walls, (see Figs. 3, 4, 6 and 7), and they eX- tend inwardly while on both runs of the horizontal carrier and while on the lower run of the inclined carrier. When they start on the upper run of the inclined carrier they are pushed up into longitudinal relation with the apron 26 by the lower end of strips 34 which are secured to the inner sides of the carrier walls 21. This action raises the tines 31 to a perpendicular position, as

shown in Figs. 1, 6 and 7 where they aremaintained by the strips 34 until the top of the inclined frame is reached. The tines are then thrown over until they come in contact with the top edge of a flat wall 35 which brings and holds them up against the apron 26 while on its downward trip. A floor 36 on the horizontal portion of the frame serves a similar purpose as the wall 35 on the inclined portion. It may be noticed that a space is left open between the adjacent ends of the wall 35 and floor 36 so that the straight tines 31 will not bind when passing over the roller 24. For the same reason the left end (see Fig. 6) of the floor 36 is terminated before reaching the roller 23.

The shafts 37 and 38 of the two rollers 23 and 24, are respectively provided with bevel pinions 39 and 40, which mesh respectively with bevel pinions 41 and 42 which are fixed on a shaft 43, journaled in suitable bearings 44. One end of the shaft 43 is provided with a sprocket gear 45 which is connected sprocket c Mounted to oscillate in the rear part this frame 53 is a shaft 5a, which is provided With a plurality of forwardly ten'ding integral gathering prongs 8, which rest with their middle parts on the offset portion 55 of a shaft 56. One end of the shaft 56 is provided with a lever arm 57 which is pivoted at 58 to a long rearwardly extending connecting rod 59. The rear end of the rod 59 is pivoted at 60 to foot lever6l, which in turn is pivoted at 62 to the tongue 12 nearthe platform When tlie prongs '8 are in raised position, as shown, the center 60 is slightly lower than the center 62:so that the weight of the prongs will lock themselves into lifted position when the joint 60 ispressed down by the foot of the operator of the machine. When he desires to let the prongs 8 down into operating position-he merely steps on the toe piece 63 of the lever 61 until the center 60 is raised above the pivot 62, when it will .swing upward and backward allowing the prongs to come down.

A third shaft 64- is mounted in the frame '53- andon'it are provided two series of oppositely directed and slightly curved picker prongs65. On one end of the shaft 6 L is a sprocket ear 66 which is connectedby a hain 67' to a sprocket gear 68 fixed on and driven by the shaft l8.

' In=Fig.. 2 is shown an improved construction of'tin'e tip especially adapted for use on the gathering tines or prongs 8. The tlneis provided with a knob 69 on its under sidewh-ich'ride's on the ground, while in its 'GIIdilS' inserted a pm 70 which is yieldingly held in extended position by a spring 71. Thus'the tine is provided with a comparatively sharp point, but if-such point should meetwith any obstruction it will yield rear ward-1y into the tine which will then, by i reason of the knob 69 pass 1 thereover,

[In the operation of the machine, when o'cks are "to be gathered, the gathering prongs-8 erslowered until they rest on the ground. --The machine, to the double trees 18 'of which -are hitched the horses, is pushed over the ground. As the prongs 8 are pushed unden-a-shock the picker tines 65 engage the bundles of grain and throw them back onto the' hor-izontal carrier. As the apron 26 starts on its upward course in the inclined-carrier frame, the tines 31 as they are brought to the perpendicular position,

wheel supported frame adapted to be p:

transversely on said fr -roe, enr e as above described, prevent the bundles from rolling backward. As the bundles are carried to the top of the elevator they are thrown over into a wagon (not shown),

which travels along with the machine.

Having now therefore fully shown and described my invention what I claim'to be new and desire to protect by Letters Patent is:
